JOHN B. PRICE, OF VOLLASTON, MASSACHUSETTS.

LAM P-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 477,267, dated June 21,1892. Application filed January 29, 1392- Serial No. 419, 717. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN B. PRICE, a citizen of Wollaston, in the countyof Norfolk and State of Massachusetts, have invented certain new anduseful Improvements in Lamp-Extinguishers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in lamp-extinguishers, the objectof the invention being to produce devices which shall. operateautomatically and effectually to extinguish the light when the lamp isoverturned or unduly jarred.

A further object is to produce a lamp-extinguisher which shall be simplein construction and which shall be effectual in the performance of itsfunctions.

WVit-h these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view of alamp-burner having my improvements applied thereto. Figs. 2, 3, 4, 5, 6,7, 8, and 9 are detail views. Figs. 10, 11, and 12 are views ofmodifications of certain parts.

A represents a lampburner, B the wicktube, and C the device formanipulating the wick D. Soldered or otherwise secured to theburner-frame at the ends of the slot through which the wick passes aretwo tubes a a, which extend upwardly within the burnerframe anddownwardly some distance below the said frame. Fitted loosely andadapted to have a sliding movement in the tubes at are two rods 17,which extend at their lower ends to points in proximity to the lowerends of the tubes a, and at their upper ends are secured to an oblongcollar or extinguisher b, which embraces the upper end of the wicktubeB, said collar or extinguisher being adapted to be moved upwardly bydevices hereinafter to be described to a sufficient extent to inclosethe flame on the end of the wick, and thus extinguish said flame.Connected to the lower end of the tubes a is a yoke a, made of materialcurved in cross-section and provided with ears 0, whereby to connectsaid yoke with the tubes a. Located be-' tween the sides of the yoke cis a slide d, the upwardly-projecting portions d of which are adapted toslide in the sides of the yoke and projectinto the tubes a, where thelower ends of the rods b rest upon them. Atthe center of the slide cl apin or projection e is located, and depending from the center of saidslide is a stem e, which latter passes freely through an opening 6 inthe cross-bar of the yoke c. A coiled spring f encirclesthe stem 6, andtends to normally force the slide cl and the parts supported therebyupwardly. Thus it will be seen that when the movement of the slide isnot prevented the spring will cause said slide, the rods 1), and collaror extinguisher b to move upwardly and smother the flame on the wick byinclosing the same Within said collar or extinguisher Z).

Soldered or otherwise secured between the tubes at is a cross-bar g,having an opening g'in its center for the reception of the headed stem hof a weight E, said weight being pendulously suspended from saidcross-bar. The weight E is preferably made cone-shaped, and near thelower end of said weight a ring or guide z'is soldered or otherwisesecured to the tubes at, and serves to limit the pendulous movements ofthe weight.

In the lower end of the pendulous weight E a conical recess j is made,and the stem his projected through this'recess and preferably slightlybelow the lower end of the weight.

Normally and when the lamp is in an upright position the lower end ofthe stem h is directly over the pin or projection e, so that the latterwill engage the former, and the extinguisher will be thus prevented frommoving upwardly and the light on the wick will remain undisturbed.Should the lamp be overturned or unduly jarred, the weight E will swingso as to carry the stem h out of alignment with the pin ouprojection e,and the slide cl will be permitted to be forced'up by the springf andthe extinguisher 1) moved up above the upper end of the wick-tube, andthus extinguish the light. By the construction and arrangement of partsabove described the extinguisherb and the rods b, attached thereto, maybe readily removed for cleaning.

In order to protect the devices which operate the extinguisher, they areinclosed by a cylinder F, preferably of sheet metal, as shown in Figs. 6and 9.

Instead of providing the yoke c the tubes a may be extended and providedwith recesses 70, as shown in Fig. 12, in which case springs 70' will bearranged in the lower ends of said tubes and the slide provided withprojections k adapted to enter said springs.

If desired, the construction shown in Fig. 10 may be adopted, in whichcase the springs Zare arranged in the tubes 11 (which are somewhatenlarged for the reception of said springs) within the burner-frame andadapted to encircle the rods 1). With the construction the slide 61 willbe made integral with the rods 1), as shown in Fig. 11.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a lamp-burner, a wick-tube, an extinguisher,and rods extending downward from thelatter, of spring mechanism forthrowing the extinguisher over the flame to extinguish it, and a gravitydevice interposed when in its normal position between the extingusherand its rods, whereby v to hold the extinguisher away from the wick,substantially as set forth.

2. The combination, with a lamp-burner, of tubes'secured thereto, rodsextending through -1 said tube, a collar secured to the upper ends ofsaid rods and loosely embracing the wicktube, a slide adapted to receivethe lower ends of said rods, a spring bearing on said slide and tendingto force it upwardly, a pendulous weight adapted to normally prevent theupward movement of the slide, and a cylinder or drum inclosin g theparts which control the operation of the collar or extinguisher, sub-'stantially as set forthv 3. The combination, with a lamp'burner, oftubes secured thereto, rods passing through said tubes, a collar orextinguisher secured to.

jecting upwardly from said slide, a cross-bar between the tubes, aWeight pendulously suspended from said cross-bar and having a recess inits lower end, and a stem extending from the weight and'through saidrecess, said stem being adapted to receive the pin on the slide when thelamp is in an upright position, said pin being adapted, when the lamp isoverturned or unduly jarred, to enter the recess in the weight, and thuspermit the upward movement of the collar or extinguisher to extinguishthe light on the wick, substan tially as set forth.

i. The combination, with a burner, of tubes secured thereto, rodsextending through said tubes, an extinguisher or collar secured to therods and adapted to loosely embrace the wicktube, a yoke removablyconnected with the tubes at their lower ends, a slide mounted in saidyoke, a stem projecting from said slide and through said yoke,-a springencircling said stem, a pin projecting upwardly from the slide, across-bar between the tubes, a weight pendulously suspended from saidcross-bar and having a recess in its lower end, and a stem projectingfrom said weight and through the recess in the weight, said stem beingadapted to remain normally in line with the pin on the slide, said pinbeing adapted to enter the recess in the weight when the stem of theweight moves out of line therewith, substantially as and for the purposeset forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

John B. PRICE.
